On my 2011 A.I. I find that the 'cut-out' section of the front inner corner of the tramps fits very poorly over the newer (V2?) AKA knuckle joints.

On the older style AKAS with the retaining pins, the fit is very well, but on the newer style AKAS I find that the cut-out section isn't the correct size and shape to clear the rather bulbous knuckles.
